a phase 2 trial of mln8237 in adult participants with acute myelogenous leukemia and high-grade myelodysplastic syndrome

Conditions: Acute Myelogenous Leukemia; High-Grade Myelodysplastic Syndrome

Summary: this is an open-label, multicenter, phase 2 study of alisertib (mln8237) in participants with acute myeloid leukemia (aml) or myelodysplastic syndrome (mds).

the drug being tested in this study is called alisertib (mln8237). alisertib is being tested to treat people who have acute myeloid leukemia (aml) or high-grade myelodysplastic syndrome (mds). this study looked at the antitumor activity in people who received alisertib. the study enrolled 57 patients. participants were categorized by disease sub-types aml and mds. participants received: • alisertib 50 mg all participants took alisertib capsules every 12 hours each day for 7 days followed by a 14-day rest period in 21-day cycles for approximately 26 cycles. this multi-center trial was conducted in north america and france. the overall time to participate in this study was until there is evidence of disease progression or unacceptable treatment-related toxicity. the participant could continue treatment beyond 12 months if it was considered by the sponsor and the investigator that they would derive benefit from continued alisertib treatment. participants had weekly blood work and clinic visits, with disease assessments every 2 cycles (ie. every 6 weeks) up to and including cycle 16. reduced visits (every 12 weeks) were conducted for participants tolerating treatment beyond cycle 16 and for participants off treatment without disease progression.
